There is no single “normal” blood pressure for each age. For most adults, the same general blood pressure categories apply regardless of age.
Blood pressure categories for adults
| Category | Systolic (top number) | Diastolic (bottom number) |
|---|---|---|
| Normal | Less than 120 | Less than 80 |
| Elevated | 120–129 | Less than 80 |
| High blood pressure (Stage 1) | 130–139 | 80–89 |
| High blood pressure (Stage 2) | 140 or higher | 90 or higher |
| Hypertensive crisis* | 180 or higher | 120 or higher |
*If you have a reading this high, especially with symptoms such as chest pain, shortness of breath, severe headache, confusion, or vision changes, seek immediate medical care.
Does age change what’s normal?
Blood pressure tends to increase with age, but that doesn’t mean higher values become “normal” or ideal. Many healthy older adults can maintain blood pressure below 120/80 mmHg, although treatment goals may be individualized based on overall health, medications, and other medical conditions.
Tips for getting an accurate reading
- Rest quietly for at least 5 minutes before measuring.
- Sit with your back supported and feet flat on the floor.
- Keep your arm supported at heart level.
- Avoid caffeine, smoking, or exercise for about 30 minutes beforehand.
- Take two readings 1–2 minutes apart and average them if possible.
If you tell me your age and your blood pressure reading (for example, 128/78), I can help interpret what it means in context.
